## Usage

The following workflows will execute a Gradle build on ubuntu, macos and windows.

The only prerequisite is to have Java installed: you define the version of Java you need to run the build using the `actions/setup-java` action.

All subsequent Gradle invocations will benefit from this initial setup, via `init` scripts added to the Gradle User Home.

### Use the action to setup and execute Gradle
|
|
||||||
|
|
||||||
The `gradle-build-action` can also be used for the actual Gradle execution, by providing an `arguments` parameter.
|
|
||||||
The following workflow is effectively the same as the one above, without using a separate `run` step.
|
|
||||||
|
|
||||||

arguments: build

```
|
|
||||||
|
|
||||||
### Multiple Gradle executions in the same Job
|
|
||||||
|
|
||||||
It is possible to configure multiple Gradle executions to run sequentially in the same job.
|
|
||||||
The initial Action step will perform the Gradle setup.
|
|
||||||
|
|
||||||
```yaml
|
|
||||||
- uses: gradle/gradle-build-action@v2
|
|
||||||
with:
|
|
||||||
arguments: assemble
|
|
||||||
- uses: gradle/gradle-build-action@v2
|
|
||||||
with:
|
|
||||||
arguments: check
|
|
||||||
```
|
|
||||||
|
|
||||||
The same can be achieved with a single `gradle-build-action` step and multiple `run` steps.
|
|
||||||
|
|
||||||
```yaml
|
|
||||||
- uses: gradle/gradle-build-action@v2
|
|
||||||
- run: ./gradlew assemble
